What protocols does Workbench support?

Can I use Workbench with any Windows PC?

Workbench requires an AVB capable Ethernet network adapter. Most network adapters do not support hardware time stamping, or traffic shaping. Currently, Workbench requires either the Echo Streamware NIC-1 PCIe network adapter, or one of the Streamware Analyzer mini PCs.

Does Workbench support the PTP best master clock algorithm (BMCA)?

The master clock is manually configured by the user. Workbench may be set to act as either a PTP grandmaster, or as a clock follower.

Can Workbench synchronize to an incoming clock reference stream?

Yes. If you set one of the Listener streams as a clock reference stream, then that stream becomes the media clock master. Any Talker streams will be transmitted in sync with the incoming clock reference stream.

Does Workbench use hardware or software timestamps? How accurate are the timestamps?

Workbench requires an AVB-capable network adapter that supports hardware timestamping, such as the NIC-1. For the NIC-1, timestamps are recorded by the hardware at the MAC at the start of the SOF octet with a resolution of 8 nanoseconds.
